Shahab | Runs | data synch on WWW server |
Data is being shared on the WWW server.
Time difference between the analyzers is in order of seconds:
time stamp of the 245MHz data is leading those of 410MHz by 21.733 [s] |

We see that intensity stabalized at 9E8 which is smaller then before.
We neticed this at 2:50, keep observing. |

Guy Leckenby (Canadian beaver team) | Analysis | e143_analyser.py Summing Script |
I've written two scripts that others might find useful for the on-line analysis.
1. The first is a simple bash script that runs a for loop to run the e143_analyzer.py script for a sequence of start values (-s). You'll need to change the increment and
start/end of the for loop to set the time resolution.
2. The second is a root script that takes the above generated scripts, reads the histograms, and then fills a 2D histogram. You'll need to adjust the TH2 bin number to
match both the bin number of the TH1s and the number of analysed files. I've included a print line to help identify the TH1 bin number.
To see the first results, I've attached a sum of July 1st 22-23h data. Sadly, I don't see any indication of the isomer, or at least the production is very low. |

Helmut Weick | Simulations | frequency list for 70Se setting |
EXCEL table with all possible fragments injected into ESR.
The path length in ESR, gamma_t and harmonic are adjusted to the 72Ge data.
Some lifetimes are limited but all intense lines are >30s in lab system.
There are two versions (for cooled beam with fixed v or uncooled (isochronous)
with fixed average Brho, take the second (grey) column.
For larger frequency shifts harmonics will overlap.
You can add more isomers. |

Helmut Weick | Analysis | maybe frequency ID |
We think we see the frequency range of A/q=2.25 at 243.1 MHz.
This would correspond to L=108.2m and E=386.4 MeV/u (gamma_t = 1.3955) at h = 126.
Path length is a bit short, for L=108.4m it should be 370.6 MeV/u.
(later reanalysis shows the measured frequency corresponds to 108.38m, which is like expected)
We closed scrapers on arc outside and straight section outside to limit Brho from both sides.
GE02DS3HG = -35mm, GEEXDS2AH = -25mm
Expected frequencies see below: |

Helmut, Yuri | Accelerator | move scrapers to see effect on unknown lines |
We close the arc inside and straight section inside scrapers to narrow and cut the 70Se line.
Then look what the other lines left of 70Se will do.
1st series with E01DS_HI
-58 - intensity as before
-52 - still as before
-50 - still full
-45 - less intensity but about same width
-40 - almost gone
0 - gone
-58 - back to old position
2nd series with EEXDS1HG
16.0 - full
15.0 - full
12.5 - less
10.5 - less intensity
9.7 - appears only sometimes
8.2 - gone
10.8 - middle intensity and more narrow, measure for a while |

Iris, Chris G. | Analysis | offset btw png and tiq files from server? |
This might have been answered before but I looked at one png file and one tiq file from the same run that was stored on the server. There seems to be an offset of 2.2 s. The png file from the server (right) shows the injection at ~5s, whereas when I look at the tiq file in the GUI (left), the injection is at ~2.8 s???? Is the looper introducing this offset? |
